Date: Wed, 26 Oct 2022 09:08:40 +0000	[thread overview]

            Bug ID: 1114
           Summary: build failures with clang 15
           Product: DPDK
           Version: unspecified
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: other
          Assignee: dev@dpdk.org
          Reporter: alialnu@nvidia.com
  Target Milestone: ---

DPDK build fails with clang 15 in Fedora Rawhide due to unused variables:

lib/eal/common/rte_service.c:110:6: error: variable 'count' set but not used
[-Werror,-Wunused-but-set-variable]
lib/vhost/virtio_net.c:1880:11: error: variable 'remained' set but not used
[-Werror,-Wunused-but-set-variable]
drivers/bus/dpaa/base/qbman/bman.h:522:6: error: variable 'aq_count' set but
not used [-Werror,-Wunused-but-set-variable]
(And in many other places).

Probably caused by this change:
https://releases.llvm.org/15.0.0/tools/clang/docs/ReleaseNotes.html
> -Wunused-but-set-variable now also warns if the variable is only used by
> unary operators.
